A recent study in the medical community has shown a decrease in teen suicide, particularly among high schoolers who are sexual minorities, since same-sex marriage was legalized. This is evidence that change in social policy impacts health outcomes among those who experience discrimination. This is important because social science has documented the negative impacts of gender and racial discrimination on mental and physical health.

A person’s status as a racial or sexual minority impacts their exposure to stress through perceived discrimination — a key way that racial, gender, and class inequalities in physical and mental health occur. The centrality and/or visibility of racial or sexual differences in a person’s life affects if and how often discrimination is perceived — the higher the salience or visibility of one’s racial or sexual identity, the higher level of perceived discrimination and the higher level of stress that person experiences.

Those who are disadvantaged in multiple ways, like being both a racial minority and a sexual minority, find themselves at higher levels of exposure to discrimination and have higher rates of depression and worse self-rated health.
